Note to self (what I think, maybe wrong): why is NaCl absorbed in the vasa recta only to a certain point and then it is secreted again? Because as it is being absorbed, the interstitium gets hypotoner and the gradient direction switches. NaCl has to go back to the interstitium to make it hypertone again. This can happen because the flow is slow enough to make the interstitium hypotone for a little while and get the gradient to switch and then the blood is gone before it can reabsorb NaCl again (reswitch). 10:12
I couldn't realize the role of vasa recta as I see its both parts cancel each other and adds nothing to the hypertonicity of the interstitium. Could you help me in that dr😑😑
Vasa recta transfer nacl back to interstitium every time during this process , the quantity of nacl increases in interstitium,where this many molecules of nacl goes ??
7:08 Mam isnt it the descending limb!!??? here im getting stuck...plz reply.....do,we determine ascending and descending on,basis of direction of filtrate??
@@quickquick472t if we throw it back, and we start another cycle the loop of henle will give another solites and go on, now the meddula will keep being hyper tonique more and more than 1200 only
In the descending limb of the vasa recta, when Nacl is absorbed shouldn't water follow it ??.. how is it the descending limb of the vasa recta takes in salt and give out water?
When blood flows down through descending limb of vasa recta there is increase in osmolarity(concentration) in surrounding so as water goes from high concentration to low concentration it goes out from vasa recta thereby increasing its osmolarity
Mam pls explain this qstn asked in NEET 2019 Use of an artificial Kidney during Hemodyalysis may result in a)Nitrogenous waste build up in the body b)Non elimination of excess K ions c)Reduced absorption of Ca2+ from GI tract d)Reduced RBC production Which of the following is most appropriate 1) c and d 2) a and d 3)a and b 4)b and c
1 Explaination: Artificial kidney cannot produce vitamin D so calcium will not be absorbed from GIT and it will also not be able to produce erythropoietin due to which RBC production will be decreased
Excellently explained!!!
Thanks madam. It's very useful for us to understand counter current multiplier mechanism.
Thanks madam. It's very for us to understand counter current multiplier mechanism.
in-depth and concise explanation and it helped a lot especially to explain to middle schoolers. Thank you for this video!
Gr8 help, thank U ma'am 😊😊
I was remaining so doubtful in this topic for a long and now iam fully cleared with this topic after watching ur video.thank u mam thanksalot🎉
Well explined and clearly understood.Thanks a lot😊
Thank you madam.
For your excellent teaching.
👏👏👏👏❤❤
Thank you very much for the wonderful explanation!!!
Thank you madam.
Nice explanation.👏👏👏👏❤
Gr8 explanation ma'am, helped me to get it crystal clear.
Well explained 👍👏
Nin ammun thanks ma'am
Nkn sike explanation
Once again thanks 🙏🙏🙏
Well done ❤❤
That was so much helpful
I listened many lectures, watched many videos and I'm cleared at this lecture
Thanks Alot Maam! Such a clear explanation! I am referring these videos in my Master's in Zoology for Physiology Paper and it is so helpful.👍🏻
All the best
Thank u mam.concept clear 💓 😘 💖
You are talented.
Thank you very much. 🙏
Good job❤
It's so clear mam
loved it alot!❣️
I am struggling from 2days to understand it .thank u soo much mam

omg i finally understood, i cant thank you enough
Thanks madam bt also talk about the counter current mechanism in thermoregulation
Thank you mam 🙏🙏❤️❤️
Thanks I understand it now ❤❤❤

Could you help me in that dr😑😑
Thank you
This is so clear omg!!!🥺
Finally I got this explaination in English..👍.as most of this explaination are in Hindi!
Thanks much
Thankuuu madam... Can u Do more videos
Thanks a lot
Thanku mam
Thank you❤
👌
Thankyou madam
Mam plz upload videos on plant haplontic diplontic cycle
that all no need! leave those topics waste topics
Good and nice but I would. Like you to hilight on reproduction in plants
Can they be blocked? How and why
Good explanation madam,
Make a video on Muscle contraction theory that is sliding filament theory.
I already have, you can check it out!

Yes, descending and ascending is on the basis of direction of filtrate.

Not Bad.
Question: why does the vasa recta (ascending limb) need to give NaCl back to the interstitium?
To maintain the osmolarity in medullary interstitial fluid which is already created by counter current multipliers
@@quickquick472t if we throw it back, and we start another cycle the loop of henle will give another solites and go on, now the meddula will keep being hyper tonique more and more than 1200 only

Ma'am I understood clearly
I was struggling to understand this concept
Thank you ma'am ❤
Achhe videos pr kam ho like hote hai !
Explanation is good mam but it's too fast to understand the concept clearly.
Thanks 😭🤍🤍🤍🤍🤍

Mam pls explain this qstn asked in NEET 2019
Use of an artificial Kidney during Hemodyalysis may result in
a)Nitrogenous waste build up in the body
b)Non elimination of excess K ions
c)Reduced absorption of Ca2+ from GI tract
d)Reduced RBC production
Which of the following is most appropriate
1) c and d
2) a and d
